麦叶灰潜蝇为害大麦、元麦、小麦叶片。每年发生一代,以蛹在土内越夏过冬,2月底至3月中旬羽化为成虫。产卵于麦叶端部。卵期平均11.7天,发育起点温度6.6℃,有效积温55.3日度。幼虫历期11天,发育起点温度5.5℃,有效积温101.6日度。幼虫孵化后,由叶尖向茎部潜食产生锈褐色虫道。三龄开始暴食形成虫泡。老熟幼虫刮破麦叶入土化蛹,入土深度在5厘米以内。在卵孵高峰后5～7天用敌敌畏、乐果、辛硫磷、甲胺磷、久效磷等农药喷雾防治均有良好效果。
Leaf damage leaf miner barley, wheat, wheat leaves. A generation occurs each year, pupae in the soil over summer and winter, from the end of February to mid-March emergence into adults. Spawning on the tip of the wheat leaf. Eggs average 11.7 days, developmental starting temperature 6.6 ℃, effective accumulated temperature 55.3 days. The larvae duration of 11 days, the development of starting temperature of 5.5 ℃, effective accumulated temperature of 101.6 days. Larvae hatch from the tip to the stem potential food rusty brown worm. Third instar began to eat bulimia bulimia. Mature larvae scrape the wheat leaves into the pupation, depth of 5 cm or less. 5 to 7 days after the egg hatch peak with dichlorvos, dimethoate, phoxim, methamidophos, monocrotophos and other pesticide spray prevention and treatment have a good effect.
